The regiospecific synthesis of the 2-oxazolidinones 5b, 7, 12a, and 12b starting from L-histidine la is described. The stereoselectivity in the dibutyl(trifluoromethylsulfonyloxy)borane promoted aldolcondensation between the chiralimides 13a and 13b and benzaldehyde was also studied. The formation of a cationic imidazole–boron complex, 14a, occurs before the aldolcondensation between 13a and benzaldehyde
